What it calculates
Derives output bytes from input key material using PBKDF2 or HKDF.
Inputs and methods
HEX or ASCII input, HEX salt, SHA-256/384/512, output length; PBKDF2 iterations or HKDF info.
Worked example
PBKDF2, SHA-256, ASCII password, salt HEX 73616C74, 2 iterations, 32 bytes.

Specification and limits
The two-iteration example is for reproducibility, not password protection. HKDF is not password stretching.
